Description

  The present invention relates to a detachable holding device, and a scattered salt capturing device that includes the holding device and captures the salt scattered in the atmosphere in order to measure the amount of scattered salt.

  In order to predict salt damage caused by sea salt particles such as insulators and steel towers in power transmission systems, the amount of salt scattered in the atmosphere (hereinafter, the amount of salt contained in the unit volume is the amount of salt in the air, and this is multiplied by the wind speed). It is necessary to measure the amount of salt (sprayed salt content), and for that purpose, it is necessary to capture the salt scattered in the atmosphere. The dry gauze method stipulated in JIS Z2382 is to install gauze in a wooden frame with open windows and install it in a well-ventilated place where it does not get wet in the rain. It is made to adhere and the amount of the attached salt is measured.

  In addition, in the outside air introduction device described in Patent Document 1, a tape-like salt removal filter is provided in the outside air introduction portion that introduces outside air into the outdoor structure, and salt is captured by the salt removal filter, thereby Prevents salt from entering the interior of the outdoor structure. Here, in the outside air introduction device described in Patent Document 1, a new surface of the salt removal filter is sent to the outside air introduction unit, and a mechanism for retracting the surface on which the salt is attached from the outside air introduction unit is continuously provided. Capable of capturing salt.

  Further, a spring 138 as an urging member is disposed between the upper part of the attaching / detaching part 120 and the upper part of the fixing part 110, and the attaching / detaching part 120 is urged downward by the spring 138. Thereby, rattling in the fixing part 110 of the detachable part 120 can be suppressed.

  Moreover, in the scattered salt content capturing apparatus 10 according to the present embodiment, the salt content capturing body 20 is installed in the leaf box 1 provided with the louver 2 on the side surface, so that the salt content capturing body 20 has a roof at the installation location. An amount of salt corresponding to the wind speed can be attached so as not to be affected by rain.

  FIG. 19 is an elevational sectional view showing a modification of the operation mechanism 30. As shown in this figure, in this embodiment, one end of the rope 32 is attached to a floor surface, a structure, or the like below the hundred-leaf box 1 via a spring 39. The spring 39 is a tension coil spring, and the spring 39 is elastically extended and the rope 32 is in a tensioned state.

  Here, the elastic coefficient of the spring 39 is set to be lower than the elastic coefficient of the spring 138 so that the force of pulling down the rope 32 by the spring 39 does not exceed the force of pressing the detachable portion 120 by the spring 138. . As a result, the rope 32 can be held at a fixed position without being loosened, and the function of the lock mechanism 130 can be prevented from being hindered by the tension of the rope 32.

  As mentioned above, although the form for implementing this invention was demonstrated, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and equivalents thereof are also included in the present invention. For example, in the above-described embodiment, the present invention has been described by taking as an example the case where the installation target installed at a high place is the scattered salt capturing body 20, but for other installation targets such as various sensors and light bulbs. However, the present invention can be applied.

  Further, in the above embodiment, the detachable part 120 is attached to and detached from the fixed part 110 by pulling up the detachable part 120 with the rope 32, but the detachable part 120 is pushed up with a stick. May be configured to be attached to and detached from the fixed portion 110. Furthermore, in the said embodiment, although the salt content capturing body 20 was made into the cylindrical shape, it is good also as other cylindrical shapes, such as a rectangular tube shape.
